Also, what you are assuming EnergyKnife is that they settle an inhospitable world. For those, yes, you would need convoys of supplies, but you could also build Biodomes to increase self-sufficiency.

Furthermore, there are going to be hospitable planets as well where conditions will be similar to your own planet, and you won't have to send them as many supplies.

Yes, I understand that there will be some hospitable worlds. But they will have to be very rare, pertaining to the fact that we still haven't found a habitable planet. I do wonder, what will be the chances that a Goldilocks Planet is habitable? Mars is in the Goldilocks zone and Venus is close, but neither is habitable. Maybe we should split the Goldilocks zone into parts, and only planets that share the players part of the Goldilocks zone are habitable.

. Also remember life can exist in volcano vents to high in the cold atmosphere so something could evolve to be cave or underground dwelling life exists everywhere so life could be common

The main reason hospitable planets are hard to find is because we are bad at finding extrasolar planets. It is very difficult to spot planets the size of Earth, or even planets in general, since the dark side of any planet is the side that faces outwards, and the bright side is facing the star so the glare of the star makes it harder to see the planet. They can sometimes be found by spotting a decrease in the brightness of the star as the planet passes in front of it, but that usually requires a planet large enough to block out a significant swath of light, and such planets are usually gas giants.

Another method to find planets is to see the wobble of a star as it rotates. Stars with wobbles are experiencing a gravitational pull from something that is orbiting them, aka a planet. However, the case is again that gas giants are usually the only planets to cause significant enough wobble for us to discern.

Moreover, we have found planets that are estimated to be hospitable, and we have found extrasolar planets that are in the Goldilocks Zone (not in the extreme ends like Venus and Mars).

And lastly, just because we haven't found many hospitable planets does not mean that they aren't out there. We are very limited in our current technology pertaining to space exploration. We can safely include decent amounts of hospitable planets in the game to expand gameplay without directly contradicting realism.

Also, if you are wondering on how to calculate hospitable planets, this has already been done by ExtraSolar and been documented in the wiki, so make sure to read up on that first.

Yes, I do know about those, such as Kelper-22b. I'm just saying that currently they seem rare.

Well that, lad, is because, in comparison to the universe, we are as atoms to an ever expanding star.

For all we know, it could be that life is just scarce in our little area. We just don't know, because we haven't really gone out and tried to say hello to the neighbors, we just send them annoying e-mails with Elvis recordings attached... .3.
